Very quiet around here I think there is football going on.
Inlet manifold drilled and tapped for Flash lube jets.
The worst bit was the first drilling, as there was no way back!
After some fiddling got the tubes to fit nicely. I wanted them concealed inside the inlet, not on show.
Cable ties secure the small manifolds that supply the flash lube to each port.
As you can see there is a lot going on in the gap between the 2 halves of the manifold, but it is relatively easy to separate them.
This will be the route the Flash lube tube will go to get to the bulkhead. The vacuum tube for the map sensor will be routed the same way.
The jets holes are drilled and tapped, then I used pipe seal to seal them.
The flash lube jet position is not important, but should be at 90deg to the airflow to ensure Flash lube is drawn through.
This is one of the LPG jets, they must be fitted as close as possible to the petrol injectors, this is to ensure good idle, fast switchover with no stalling between petrol/gas, and to get the injection timing more accurate for efficiency.
They have to be at 90deg or less, they don't have to point at the back of the valves like petrol injectors, as the gas will not condensate on the inlet walls like petrol will.
This is where I plan to fit the LPG jets, that is as close as I can get whilst still being able to access the bolts that hold the inlet on. I don't want to fit them underneath as oil or dirt could collect in them.
They are M10 x 1.0 which I didn't realise I don't have a tap for, so I have had to order one.
The LPG fitter I got the kit from said normally the jets are drilled without taking the manifold off, using a special drill with a hoover on and a tap covered in grease. I imagine you would get your jets fitted wherever the drill can reach. I didn't fancy that idea...
